Fortunately her mum and her are the same size. So I fitted the skirt to Sherrie and brought a few pieces of fabric over under the disguise that it was all for Sherrie. Asked Monique which was her favorite...and so here it is.
I used S2254 but lengthened the tie and didn't stitch it onto the skirt. Instead I added belt loops (so a different belt could be worn too) and made the belt separately.
